## Description

desertcart.com: Hot Shot's Secret LX4 Lubricity Extreme 1 Gallon, Fuel Treatment for All Engines, Gasoline & Diesel Additive, Fuel Additive Increases Lubricity, Protects & Extends Fuel System Life : Everything Else

Review: Perfect for my Ford Explorer 2013 - I must say that I up keep my Explorer in everyway, oils changes on time religiously, coolant flush on time, all scheduled maintenance done on time, but I drive a lot of miles, 124 miles Monday through Friday, more when I have to pick up my daughter. So the wear and tear happens no matter the upkeep. Lately I've felt the car somewhat sluggish and I happen to fall upon this and read what it offers and decided to give it a shot based on the reviews. I must say that the difference was night and day, the car became more quiet, drove smoother, enhanced performance on the highway, it was a real noticeable difference. It just felt so much better when I put my foot on the pedal. Now with that said, I really didn't noticed better MPG, and maybe that was because I upkeep and baby this car. This was very simple to use, simply use 2 oz per fill up, you squeeze the bottle and it has a 1 ounce fill cup on the top of the bottle which is beyond helpful to make sure that you do not over use. I've driven over 2k miles since using this and I can assure you that it will not be a major part of my upkeep.
Review: great stuff been using for years and hundreds of miles.. :) - been using in my 2003 7.3L we got in 2015 and now in 2017 ram 6.7l cummins we got in 2024.. keeps thing clean adn running smooth.. does it help with MPG,, not sure as I have either used HotShots or Archoil for 2 bottles then back to HS. Recently got a bottle of Power Service Diesel injector and DPF flush to help as well.. check it out..
